Figure shows a double slit located a distance x from a screen, with the distance from the center of the screen given by y. When the distance d between the slits is relatively large, there will be numerous bright spots, called fringes. It can be shown that, for small angles (where sin θ≈θ, with θ in radians), the distance between fringes is given by Δy = xλ/d. Using this result, find the wavelength of light that produces fringes 8.50 mm apart on a screen 2.00 m from double slits separated by 0.120 mm.
